Scraping: Important to remove as much food particles as possible before washing. This also means that the water in the machine does not need to be changed as often. Scrape better. Detergent and drying agent dosage: The dosing affects both detergent and drying results of the dishes. The hardness level of the water affects the consumption of detergent. Contact the detergent supplier Temperatures: At incorrect temperatures the dishes will not be clean. Contact a service technician if you need to change the set values. Programme selection: Programme with too short a washing time selected. Choose a programme with a longer washing time. Cleaning the machine: Insufficient cleaning of the machine affects the results of the washing. Ensure better cleaning of the machine. Placing dishes in baskets: Incorrectly placed items can mean that the washing water does not reach the items during washing and rinsing. Soaking: Items with hard dried food. Soak the dishes in water. Do NOT use washing-up liquid.

4.2.6 Changing the water To achieve the best possible washing results, it is important that the water is changed frequently. For normally soiled loads, the water should be changed after around 30 washes. However, always change the water in the event of foam problems in the tank. The machine can be equipped with a so called active filter (option). This means that the machine does not normally need to replace the water. However, always change the water in the event of foam problems in the tank. If IF09 appears on the display, this indicates that the water should be changed.

After use – cleaning HACCP is a preventive inspection system to ensure hygiene requirements are met during the washing process and cleaning of the machine. As a result of its design, the machine meets strict hygiene requirements. Regular, thorough cleaning is also important from a hygiene perspective. A machine that is properly cleaned helps produce a good wash result, reduces the risk of dirt accumulating, increases the service life of the machine and reduces the risk of emergency shutdown. If the machine will not be used for a longer period, the power to the machine should be turned off using the power switch, the water supply turned off and the the door should be left ajar.
